Numerical Study of Coupled Fluid Flow and Heat Transfer in A Rectangular Domain At Moderate Reynolds Numbers Using the Control Volume Method

In this paper, we have used a control volume method to investigate the problem of a fully coupled uid ow with heat transfer in a rectangular domain with slip wall boundary conditions. we have used this method to solve the governing equations and thereby to compute the convective and diusive uxes at the cell faces of the control volumes considered around the grid points of computational domain. we have used a staggered grid approach for the discretization of the governing equations. a simple algorithm was used for the discretized equations in order to compute the numerical solutions of the flow variables: velocity, pressure and temperature for moderate reynolds numbers in the range of 500-2500. we have executed this with the aid of a computer program developed and run in c-compiler. also investigated was the behavior of ow variables for reynolds numbers (ℜ) = 500; 1000; 1500; 2000; 2500 and prandtl number (pr) = 7:00. the phenomenon inside the rectangular domain was also analyzed for the streamlines and isotherm patterns for moderate reynolds numbers range. the numerical results have been obtained with desired accuracy.
